Dasysyrphus Nigricornis
''Dasysyrphus'' is a genus of hover flies with 50 identified species distributed worldwide (see distribution map). While the genus is relatively easy to identify genera key the differences between species have a more narrow range of variations. Therefore, identification of species by images of specimens alone should be made with care. (See available keys below) Larvae The known larvae are mostly tree dwelling on both conifers and deciduous trees. They feed on aphids and other small Hemiptera resting in the daytime. This nocturnal habit, plus the camouflage coloration of the larvae may account for the lack of larval reports for this genus.

Samuel Wendell Williston
Samuel Wendell Williston (July 10, 1852 – August 30, 1918) was an American educator, entomologist, and paleontologist who was the first to propose that birds developed flight cursorially (by running), rather than arboreally (by leaping from tree to tree). He was a specialist on the flies, Diptera. He is remembered for Williston's law, which states that parts in an organism, such as arthropod limbs, become reduced in number and specialized in function through evolutionary history. Early life Williston was born in Boston, Massachusetts to Samuel Williston and Jane A. Williston née Turner. As a young child, Williston's family travelled to Kansas Territory in 1857 under the auspices of the New England Emigrant Aid Company to help fight the extension of slavery. He was raised in Manhattan, Kansas, attended public high school there, and graduated from Kansas State Agricultural College (now Kansas State University) in 1872, afterwards receiving a Master of Arts from that instituti ...
